The Western 29070-1 module acts as the central hub for your snowplow’s lighting system. This genuine 3-port isolation module integrates your plow’s electrical functions with your vehicle’s wiring. It manages the headlights, turn signals, and parking lights for both 2-plug and 3-plug systems. Additionally, this “Green Label” module handles both DRL (Daytime Running Light) and non-DRL vehicles.
You will typically find the Western 29070-1 mounted under the truck’s hood. It protects your vehicle’s sensitive electrical system from feedback or shorts. Furthermore, this module automatically transfers high and low beam signals to the plow when connected. Consequently, it ensures safe and consistent illumination during heavy snow conditions.
The 29070-1 replaces the older, obsolete 29070 module. Therefore, if you have an older “White Label” module that failed, this is the correct direct replacement. Next, ensure you check your vehicle-specific headlight adapters for corrosion when installing this unit. We recommend using dielectric grease on all ports to prevent future moisture damage.
This module works seamlessly with the 35500 handheld controller. Moreover, it requires a healthy 28587 control harness for proper communication. If your lights are flickering, inspect your 72100 or 29800 lighting harnesses as well.
Specialist Tip: If you are replacing a burnt 29070-1 module, check the pins on your 28587 harness. A corroded harness is the #1 cause of module failure. Save time by replacing both at once.
Always refer to your Western Plow’s documentation and vehicle-specific wiring guides to confirm compatibility and proper installation procedures.
